Boggart

Boggarts are peon enemies who appear in groups. They generally congregate with Thresh.

Boggarts, depending on their classification, will often use nothing but melee range swipes or other attacks that require being in the target's immediate vicinity. Their mobility makes them a nuisance, but they often lack any major defence and are easily dispatched most of the time.

It should also be noted that Boggarts will occasionally be un-Fateshiftable, though this is not always the case; particularly around Threshes, they seem to have a greater chance of being Fateshiftable at times (confirmation needed).
